Remember back in the old days, when nano-scale motors were a clunky 500 nanometers across? That record was subsequently broken with a 200-nanometer model, but has now been broken again, by a motor that’s just one nanometer wide. By comparison, the width of a human hair is about 60,000 nanometers. The new motor, created by scientists at Tufts University in Massachusetts, is reportedly the first one ever to consist of a single molecule.
